General Details

Most machines such as dryers, dishwashers, pumps, compressors, motors and many other applications worldwide use motor capacitors as film capacitors with PP foil.

Due to its quality, Hydra is one of the leading suppliers of these motor capacitors, producing approximately 18 million capacitors per year.

This is the core competence of Hydra with a history of more than 100 years.

The motor capacitors can be supplied in 2 versions: Unprotected (S0) and protected (S2).

Protected motor capacitors are filled with oil and have an overpressure fuse that disconnects the capacitor in the event of a fault and therefore provides a high safety standard.
